In Widelands, you are the regent of a small tribe. You start out with
nothing but your headquarters, a kind of castle in which all your resources
are stored. Every member of your tribe will do his or her part to produce
more resources - wood, food, iron, gold and more - to further this growth.
But you are not alone in the world, and you will meet other tribes sooner or
later. Some of them may be friendly and trade with you. However, if you want
to rule the world, you will have to train soldiers and fight.
